I live in the Chicago area. When I visit various Jewish deli's I will often have the Mish Mosh Soup, which is chicken soup with rice, noodles, a Matzo Ball, a kreplach and sometimes kasha.
I was corresponding with a new Chicago Chowhound who move here from New Jersey, he commented"
"I have never heard of mish-mosh soup before I moved to Chicago (only the term mish-mosh). But I know it's on the menu at The Bagel on Broadway, and apparently also on the menu at Once Upon A Bagel. I wonder if this could be a Chicago-Jewish food concoction."
Is this a Chicago-centric offering?
